What are musical forms of padding?

The Spiderman example, is, as written, not padding. It's Arc Fatigue, Kudzu Plot and The Chris Carter Effect. Yes, it's stretching a story, but, it misses part of the definitions entirely, mainly, the very first line Padding is a moment in a story which could have easily been removed from the plot without affecting the story significantly. Those moments DID affect the story (admitably, in complex, confused and often retconned ways). While I do not doubt there is padding in the clone saga, the example, as currently written, fails to show an example of padding. I thus removed it.
